/* "Sound therapy examples", device style (TEST build, third version).
   Same family as the tone tool and the "What's my next step?" check above it: deep-brown rim with a gold hairline,
   cream face, dark screen. Left: the four sounds as coloured pads (white/pearl, pink, brown, blue for binaural) with a
   tray underneath that shows what the sound is like, or the blue binaural sliders. Right: a "now playing" screen with a
   calm level meter (moves only while playing), a thick volume slider, a big Play button and the timer.
   The page's own script still does all the sound, volume, timer and binaural work; tinnitus-therapy2.js only paints
   the slider fill, the meter, the sound name and the playing light. */
